Sanding Semi Glossy Paint?

[Negativecreep0]

ok here is the deal i bought some small cans of American standard Latex Primer and Semi Gloss Enamel Bright White. I applied one coat of the latex primer to the mdf wood. Now it is dry what do I want to do next? do i want to sand the primer? or just apply the enamel? Also how do i work with Semi Gloss enamel if i sand it wont it remove the semi gloss?


any help is appreciated this is my first paintintg project ever.

You will want to sand the primer, and than for a better finish, apply another caot of primer, and then sand that coat,

When you paint, you want to sand after every coat of paint, except that last coat, thats the one you do not sand. 

I am no painting expert, but this is what I have been told.

Hope that helps

what grit sand paper am i going to want to use for paints? somethign very fine?

[Ldsfunaz]

i used 100 for my primer, and 320 for my semigloss,
i started out trying to get away with 100 on my semigloss and that looked like poopy-pie.  I then went out and got the 320 and I am very happy with the finish

I use 320 grit between coats, whether it's primer or finish paint.

Yes, sand each coat except the last coat.  Use fine grit paper 250+.  It will look pretty rough after each sanding, but the final coat will look good and really suprise you.  Here is a pic of mine during sanding, and then after the last coat. - I also used a coat of primer and a semi-gloss for the final coat.

nice paint job what type of roller did you use? brand? also is it recommended i do 2 coats primer and 2 coats of semi gloss

[AC.]

Thanks.  I just used a cheap-o roller (a new one).  I would not do two coats of primer, I think two coats of primer are unnecessary.  However, your choice of roller and whether or not you do one or two coats of primer probably wont make much of a difference.   Post some in-progress pics and some final ones when you have it done.  Good Luck!

I'm in the process of painting my cabinet and first used a cheapo roller.  I had trouble with bits of the roller fuzz getting in the paint (it must have been a REAL cheap roller!).  I had much better luck with a foam roller.  The only problem with it is that it's only 4" wide and it would be better if it was a bit wider.

I had some of those issues when doing the lacquer coats. The J-Rcade took several coats on the CP, and I had to do alot of sanding to get it as smooth as I wanted. I forget what grit I was using at the later stages, 320 sounds about right. For the final shine, I used polishing compound and a big buffing wheel. It's gotten a few dings, but that's to be expected. I had even thought about trying to pour a hard resin cast over it, making it impervious, but that was too risky, I didn't see a way to pour something that big, and not end up with bubbles. So if it gets really bad, I can always sand down and recoat. =]

Make sure to use a tack cloth in between sandings to remove all the dust, and I would recommend a foam roller. They seem to give the best even coat.
